Provide options for comprehension

The purpose of education is not to make information accessible, but
rather to teach learners how to transform accessible information into
useable knowledge. Decades of cognitive
science research have demonstrated that the capability to transform
accessible information into useable knowledge is not a passive process
but an active one. Constructing useable knowledge, knowledge that is
accessible for future decision-making, depends not upon merely
perceiving information, but upon active “information processing skills”
like selective attending, integrating new information with prior
knowledge, strategic categorization, and active memorization.
Individuals differ greatly in their skills in information processing and
in their access to prior knowledge through which they can assimilate
new information. Proper design and presentation of information – the
responsibility of any curriculum or instructional methodology - can
provide the scaffolds necessary to ensure that all learners have access to knowledge.
